From Latin Orontēs, from Ancient Greek Ὀρόντης (Oróntēs), from Akkadian 𒀀𒊏𒀭𒌓 (Arāntu, “Orontes; site of the Battle of Qarqar”) and also in Egyptian jrnt (Arantu/Araunti, “Orontes; river flowing by Qadesh”) attested at least from the period of Ramesses II:
- The meaning of which is contested with connections to: Akkadian 𒀀𒊏𒀭𒌓 (arantu, “a type of grass; fennel”), perhaps in connection to the region around the city of Ugarit, the ruins today being known as رَأْس شَمْرَة (raʾs šamra, “Headland or Cape Fennel”).
- Also connected to Akkadian 𒀀𒊏𒀭𒁺 (araddu, arantu, “wild ass; stubborn”), possibly related to the modern name for the river الْعَاصِي (al-ʿāṣī, “rebel, stubbornly in error, refusing to be corrected”) so-called for its flowing south to the north unlike the rest of the rivers in the region.
- Disputably from Old Median *Arvand; compare Avestan 𐬀𐬎𐬭𐬎𐬎𐬀𐬧𐬝- (auruuaṇt̰-, “swift”).
- A river in Western Asia, about 400 km (250 mi) long, flowing from Lebanon through Syria before entering the Mediterranean Sea near Samandağ in Turkey.
- The name of any one of a number of ancient Armenian kings.
